我试图创建一个简单的

RestHelper

“Hello world”示例，但遇到了问题。使用

container:start

命令启动容器时

serve {
    case Nil Get _ => Extraction.decompose("Hello Restful world!")
  }

在my

RestHelper

扩展中未调用。我得到以下信息： “在此服务器上找不到请求的URL/”

所以，似乎出于某种原因，lift忽略了

LiftRules.statelessDispatch.append(Service)

定义中的行

bootstrap.Boot.Boot

。我完全不知道为什么会这样

这是我的

Boot

课程：

package bootstrap

import net.liftweb.http.LiftRules
import com.yac.restfultest.Service

class Boot {
  def boot {
    LiftRules.statelessDispatch.append(Service)
  }
}

这里是

服务

：

package com.yac.restfultest

import net.liftweb.http.rest.RestHelper
import net.liftweb.json.Extraction

object Service extends RestHelper {

  serve {
    case Nil Get _ => Extraction.decompose("Hello Restful world!")
  }

}

如果有帮助，下面是我的

web.xml

：

<!DOCTYPE web-app SYSTEM "http://java.sun.com/dtd/web-app_2_3.dtd">
<web-app>
    <filter>
        <filter-name>LiftFilter</filter-name>
        <display-name>Lift Filter</display-name>
        <description>The Filter that intercepts Lift calls</description>
        <filter-class>net.liftweb.http.LiftFilter</filter-class>
    </filter>
    <filter-mapping>
        <filter-name>LiftFilter</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>
</web-app>

正如你所见，这几乎是最简单的电梯项目设置可能。我还是不能让它工作。任何帮助都将不胜感激

下面是

所以，事实证明这是一种平常的无意识的不专注。包含

Boot.scala

的包应该被称为

bootstrap.liftweb

，而不是像我的例子那样仅称为

bootstrap

---

是的，正如jcern所建议的，它应该是路由模式中的

“index”：：Nil

。

您是否尝试过匹配：

“index”：：Nil

而不是简单的

Nil

？我甚至尝试将路由设置为“test”：：“item”：：Nil。还是没用。
